and low voltage circuits.
All circuits, except battery cables 
and AC, are power limited.
Maintain at least 0.25” spacing 
between power limited and non-
power limited circuits.
Separate high and low voltage 
circuits.
Route all low voltage 
wiring through any of 
these knockouts. 
Fire alarm power-limited circuits are 
installed using types FPL, FPLR, 
FPLP or permitted substitute cables, 
provided these power-limited cable 
conductors extending beyond the 
jacket are separated by a minimum 
of 0.25 in. (6.35 mm) or by a non-
conductive sleeve or non-conductive 
barrier from all other conductors.
